SPECIFICATION forming part 0f Letters Patent N0. 692,407, dated February4, 1902. Application filed May 9, 1901. Serial No. 59.414. (Nospecimens.)

To all whom, t may concern:

Be it known that I, WILLIAM J. WRIGHT, a citizen of the United States,residing at Pitts burg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMethods of Veaving IVire, of which the following is aspecification,reference being had therein to the accompanying drawings, forming partof this specilication, in which- Figure lis a plan view of a number ofspindles and spiral ceiling-guides assembled in proper relation toproduce a continuous woven fabric and showing the same in course ofconstruction. Fig. 2 isa cross-sectional View taken on the line II II ofFig. l. Fig. 3 is a similar view at right angles on the line III III ofFig. l, showing the coiling-guide and also the feed-rollers. Fig. 4 is aview of several pairs of interwoven coils as they are delivered fromtheir spindles -with the intervening interwoven supplementalconnecting-coil. Fig. 5 is a similar view, but showing all of the coilsequally arranged. Fig. 6 is an enlarged detail sectional view of one ofthe spindles and guides.

Myinvention consists of an improved method of weaving wire into a fabricor netting by means ofinteritting spiral coils, whereby t-he full widthdesired may be made at one time of any desired number of wiressimultaneously and continuously and in one operation. Heretofore inmaking wirework of this description it has been the practice to form buttwo intertting spiral coils upon a forming-spindle and then join eachone of such pairs of interwoven coils by a single interwoven separatecoil with the next adjacent coil of another similar pair, repeating suchoperation until the required width was obtained.

In the practice of myinvention a plurality v of spindles 2, having theusual spiral grooves 3 8, are mounted in suitable housings 4 at such adistance apart as will admit of the location between the spindles ofseparate guides 5, which for approximately the full length of thespindles are straight. These guides have in one side a groove 6 ofsufficient size to admit the wire, but partly closed, so as not to allowthe wire to escape outwardly, and at or above the delivery end of thespindles each of these guides is formed into a spiral 7 of the samepitch and relative position as the spiral grooves 8 of the spindles, thegroove 6 55 thereof being maintained on the inner side, as shown. Byreason of the close arrangement of the pairs of spirals to the nextadjacent pair it will be seen that the spiral guide 7 may be loopedthrough the alternate oppo- 6o site spiral loops of such pairs withoutinterference with the forward progress of the coils, whereby when theindependent spiral coils 8 are finally delivered from the ends of theguides 7 they will travel forward in the same 65 relation to the coils 910 from the spindles 2 and will interengage with such coils. By reasonof the close proximity of each independent pair 9 lO to the nextadjacent pair sufficient clearance is allowed for free en- 7o gagementand interaction, and it will be seen that such assemblage andinteraction of the coils wili be continuous throughout the operation. Asdelivered from the spindles and spiral guides the interwoven coils willassume 7 5 the arrangement and relation to each other shown in Fig. 4 ofthe drawings, while after having been subjected to an equal tension allover the coils will be symmetrically arranged, as shown in Fig. 5. 8o

The forward feed of the wires is accomplished by means of the customaryfeed-rolls ll, and it will be understood that such other details ofconstruction necessary to embody the invention in practical form in anoperative mechanism are properly Within the province of the designingengineer or are the subjects of other inventions and do not necessarilyform essential parts of the present invention.

It will be understood that such wires as are' referred to by the termadjacent are those wires which in the completed fabric lie adjacent toeach other and are connected by the additional wire, or, in other words,the adja- 95 cent wires 9 9, Woven by any two adjacent spindles 2 2 andare connected by the independent coil S, formed on the ceiling-guide 5and its spiral terminal 7.

It will be understood that several wires may roo be passed through oraround the same groove so as to, in effect, form one Wire, and Whereverthe term coil or other synonymous term is employed it is intended toinclude such plural wires. It Will also be understood that the fabricmay be Woven in flat form, as in making mattresses, or that the spindlesand guides may be arranged in cylindrical form, so as to Weave bags orsimilar articles.

Having described my invention, what I claim isl. The method of makingwire fabric consisting in simultaneously forming pairs of interwovenspiral coils and independently forming intervening connecting-coilsbetween such pairs, substantially as set forth.

2. The method of making Wire fabric consisting in simultaneously formingpairs of interwoven spiral coils and independently forming interveningcoils and alternately engaging the same with the adjacent members of thepairs, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
